Laptop :: Technology Best Revoulution


tealaptopandmeA laptop computer is a personal computer for mobile use. A laptop has most of the same components as a desktop computer, including a display, a keyboard, a pointing device such as a touchpad (also known as a track pad) or a pointing stick, and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. Laptops are also sometimes called notebook computers, notebooks or netbooks.

Portable computers, originally monochrome CRT-based and developed into the modern laptops, were originally considered to be a small niche market, mostly for specialized field applications such as the military, accountants and sales representatives. As portable computers became smaller, lighter, cheaper, more powerful and as screens became larger and of better quality, laptops became very widely used for all sorts of purposes.

History ::

As the personal computer (PC) became feasible in the 1970s, the idea of a portable personal computer followed. A “personal, portable information manipulator” was imagined by Alan Kay at Xerox PARC in 1968, and described in his 1972 paper as the Dynabook“.

The IBM Special Computer APL Machine Portable, was demonstrated in 1973. This prototype was based on the IBM PALM processor (Put All Logic In Microcode or 128 bit).

The main thing to think about when buying a laptop is what you are going to be using it for. There are five main types user :   

CASUAL 
Are you the sort of user who wants to use the internet, check email, watch DVDs, listen to music and not a lot more? Then you’re a casual user. People after this sort of laptop are often oversold more expensive products by pushy sales assistants as these users often know least about what they are looking for. Though it might not be light and may not be have supermodel looks but it should do everything you need it to do. Here are a few things you should look for:
Memory/Hard drive Around 2GB of RAM should suffice. You could get away with 1GB if you are not conducting multiple tasks at once. Safe to say that the more RAM the better. 
Graphics For the sort of price you are looking to spend then you are pretty much stuck with what you are given. This is generally “shared” graphics which means that the integrated card shares memory with the main operating system. Rubbish for gaming or complex multimedia tasks but fine for everyday use. 
TRAVELLER
Laptop technology is increasingly moving towards the portable end of the market and battery life of new laptops, where once a 3 hour stint without a charge was considered revolutionary, is pushing towards and even exceeding 10 hours – although this can be hard to achieve.
WeightWeight is all important. As a rule, the lighter it is the more expensive it will be. Ideally, choose a laptop with a weight around 2 kg. or less. Any more and that laptop bag will start getting uncomfortably heavy.
Battery lifeChances are that you will be away from a plug socket for long periods of time. If you’re out on the road all day then a battery life of eight hours would be ideal but very few laptops offer that. Around 4/5 hours is around the industry standard for mid-range light laptops, however laptops advertising a 12-hour battery life are now on sale, though many reviewers have said this claim is still optimistic.
SizeIf you are travelling then screen size is a compromise you may have to make. Average sizes are around 13 inches but can be as small as 10. If you are not doing complex tasks or wanting to watch DVDs then a netbook might be best. They have smaller memories and longer battery life. The thinnest laptops can be under 3cm in width but really you should aim at no more than 4cm.
Optical drivesor the lack of them. Many “ultra-portable” – as they are known – have not included a disk drive to cut down on weight and width. If you intend to watch DVDs and aren’t comfortable, or do not have sufficient free space of disk, with them on your hard drive then an optical drive is a necessity.

Hard drive If there is no internal optical drive then the hard drive needs to be larger to incorporate items that you might have kept on DVD. Around 160GB could be plenty if you don’t have a large media library. If you want to hoard every film made in Los Angeles then the sky is the limit (though most portables don’t go much about 5oo GB Sata).

Office and Business Works
Ever thought of yourself as a bit of a Rankin or a Spielberg? While video and photos can now be edited on nearly every machine you would buy (helped with Apple or Microsoft’s bundled software) if you are planning to do more complex edits then more complex software – Adobe’s Creative Suite, Pro Tools and Final Cut are good examples – will need to be purchased. Also you are wants to do office works and highly use for E – mail checking, web browsing, multimedia jobs different critical works, then you can follow this types laptop.

MemoryThe bigger the better. 4GB should be fine the moment but a new wave of machines with larger ram capacity is expected in the near future.

GraphicsImportant for editing images and video. A dedicated graphics card (with its own memory) is becoming a necessity if you want to undertake this sort of work, ranging from 128MB to 2GB. This decision has to be influenced by your budget.

PortsIf you’re using a lot of complex machinery – cameras, musical instruments etc. – then you need to make sure that it will connect to your laptop without much trouble. Standard connections should be three or four USB ports (preferably USB 3.0 though this is very new technology) and it could be the case that you need a Fire-wire port. Laptop manufacturers often choose to exclude this port.

FanIf you are recording music using your laptop then does it need to be silent? There are a number of almost silent fans on the market but are quite expensive. It is also the case that modifications to this part of the laptop can be difficult so if you require a silent machine then it may be best to consult a specialist music supplier.

DVD/Blue Ray Disk Absolutely, for your office works and critical works you must add a Blue Ray disk drive, or DVD ROM. Now, this generation time, blue ray disk is most important.       

Rest, somebody told me which is better for working : Laptop or Notebook or Net-Book. Actually Notebook mean is Laptop. Notebook is the technical name of the Laptop, but Netbook’s are different from Laptop. Netbooks are specially using for web-browsing, email checking & some office works.
But I would like to prefer to you want to use your laptop in office, home & outside, almost 360 degree angle environment, you must follow the professional level laptop but you wants to use it only in your home, then you can buy traveller based laptop.
